Adapting row height is slow

How do you view the progress and activities during the
opening of a large file?

As the sheet opens on the status bar at bottom of the Calc UI, a "Loading document" and progress bar appears, followed by the "Adapting row height" and its progress bar--when applicable to the spreadsheet.

Appearance is timer based, so high row counts and formatting being applied for large sheets trigger appearance of the progress bar. It often won't show for short sheets.

There is no manual control, nor other way to observe sheet loading directly.
